IMPROVEDINSOLE FOR BOOTS rANZI) SHOES.

The Schedulereferred to in these Letters Patent and making part of the same.

To all whom it ma/y concern:

Be it known that I, EDWIN O'HESTERMAN, ofvTre mont, in the county of W est-chester, and State of New York, have'invented a new and improved Ventilating Insole for Boots and Shoes; and I do hereby declare the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which- 1 Figure 1 is a top view of the insole;

Figure 2 is a vertical longitudinal section; and

Figure 3 is a bottom view of the same.

The same letter indicates the same part in the several figures.

The nature of my invention consists in attaching to the bottom of an insole formed of leather, or other.

material pervious to air and moisture, triangular, or otherwise shaped strips or supports of rubber, or other similar non-absorbent material, placed, preferably, par allel to each other and diagonally to the longitudinal Yand transverse axes of the sole, as hereinafter set forth.

The object of the invention 'is to provide an insole, which, while inter-posing a water-proof` and elastic material between the inner and outer soles, shall yet allow of the downward escape, through the body of the insole, of the perspiration from the bottom of the foot, thus protecting it from dampness, and providing for its free ventilation. Y

` In the drawinga marks the leather or pervious insole, and

b, the strips attached tothe bottom of it. 4

These strips or bearings may be of any desired shape, but I prefer the one represented.

The eiect of placing them diagonally is to give a much greater degree of spring to the sole than would result om placing them parallel to either the longitndinalor transverse axis of the sole. v

If placed longitudinally, the strips would be few iu number, and the spaces between them would receive air only at or near the heel and toe of the bootorshoe, which would render the ventilation imperfect.

If rubber isused for the strips, they can be united to the leather by and during the process of vulcaniza tion.

A sole made as herein described, affords a firm' yet elastic support to the foot, while by the alternate com-- pression and release which the strips undergo in walking, a pumping action is kept up which constantly' draws in and expels air, and thus maintains a perfect ventilation, and'keeps the feet dry and warm.

Moreover, by raising the foot out of contact with the outer sole, it protects it from the dampness which may rise through that sole.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent, is-

1. An insole, made of leather, supported on strips or bearings of rubber, constructed and arranged. in the p manner and for the purpose set forth.

2. An insole, formed of asuitable material pervious to air and moisture, supported upon bearings of awaterproof or non-absorbent material, all constructed, arranged, and operating as described for the purpose specified. i

The above specification of my said invention, signed and witnessed at New York, this 16th day of March, A. D. 1869.
